COMBINED HARROW AND PLANTER.

SPECIFICATION forming part of Letters Patent No. 767,280, dated August 9, 1904. Application filed February 20, 1904. Serial No. 194,545. (No model.)

To all whom it may concern:

Be it known that I, CARL AUGUST JOHNSON, a citizen of the United States, residing at Duluth,in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in a Combined Harrow and Planter; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improved seeder adapted for use in planting difi'erentkinds of grain in any desired quantities per acre; and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed.

One object of my invention is to effect improvements in the means for supporting the hopper.

A further object of my invention is to provide an angularly-adjustable hopper havinga discharge-spout the lower end of which may be raised or lowered, as may be required, by adjusting the hopper.

A further object of my invention is to effect improvements in the means for regulating the discharge of grain from the hopper to the force-feed devices.

In the'accompanying drawings, Figure 1 is a side elevation of my improved seeder or planter. Fig. 2 is a partial vertical transverse sectional view on the line 2 2 of Fig. 1. Fig. Sis a vertical longitudinal sectional view through the seed-hopper. Fig. 4 is a transverse sectional view of the same. Fig. 5 is an enlarged detail view of a portion of the feed mechanism removed fromthe hopper. Fig. 6 is a bottom plan view of the lower plate of the partition of pockets, showing the sliding cutoff plates for opening and closing the feedopenings, one side of the same showing said openings closed and the opposite side open.

pair of longitudinally-disposed supportingbars 3, to the forwardly-extended ends of which are connected the thills or shafts 4. The rear ends of the bars 8 are bent upwardly and rearwardly, and to said ends is secured a drivers seat 5.

On the bars 3, above the axle 2, is fixedly mounted a frame 6, which consists of two transversely-disposed parallel beams 7, spaced apart and secured together at their ends, as shown. On the bars 3, in rear of the beams 7 is arranged a board which forms a foot-rest 8.

Above the frame 6 and pivotally connected to the same is arranged a transversely-disposed hopper 9, the upper end of which is braced by and adjustably secured by set-screws 9, as shown, to the curved longitudinally-disposed bars 10, secured at their front and rear ends to the supporting-bars 3. On the lower end of the front side of the hopper is fixed a forwardly-inclined feed-chute 12, the upper end of which is in communication with the lower end of the hopper, as shown.

By pivotally supporting the hopper, as above described, the same may be tilted rearwardly or forwardly to raise the chute 12 to permit the barrow-frame to be raised or for any other purpose, said hopper being held in such tilted position by the set-screws 9, which are screwed into engagement withthe curved bars 10.

Within the hopper is arranged a horizontally-disposed partition 13 in the form of a series of pockets 14, the bottoms of which are inclined toward a central feed-opening 15 formed in each pocket.

Slidably mounted on the under side of the partition or pockets are two cut-off plates 16, in each of which are formed two openings 17, corresponding in size with the openings 15 in the feed-pockets 14. The plates 16 are slidably mounted in guideways 13, formed on the bottom plate of the partition 13, and are adapted to be shifted to bring the openings 17 in the same partly or wholly under or in alinement with the openings 15 of the pockets 14, thereby changing the size of said openings and regulating the feed of the seed contained in the hopper.

' In order that the plates 16 may be shifted to open and close the feed-openings, the same are provided with offset operating rods or links 16, which are connected at one end to said plates or slides and at their opposite ends to operating-levers 16 which are pivoted to the bottom plate of the partition 13, the free ends of the levers projecting out through a slot in the rear side of the hopper, as shown.

To facilitate the adjustment of thelevers when the same are operated to slide the plates 16, a gaging device is provided, said device consisting of a plate or casting a, secured to the front of the hopper. In said casting a is formed a horizontally-disposed opening or slot I), through which project the ends of the levers 16 In the slot 5, above the levers, is rotatably mounted a square bar 0, on the sides or faces of which are marked scales by which the levers 16 may be adjusted to regulate the size of the feed-openings for sowing certain quantities of various kinds of seed to the acre. For instance, on one side of the bar 0 are arranged gage-marks for sowing so many bushels of wheat to an acre, while on another side may be arranged marks indicating how many bushels of flax and oats to an acre, so that should it be desired to sow two bushels of oats to an acre the levers 16 are moved to the mark indicating that number, and when the levers are so moved they will adjust the sliding feedplates 16 to open the feed-openings to the proper size to discharge this amount of seed to an acre.

In order that the levers 16 may be accurately adjusted, a sliding plate or bar (Z is adjustably secured to the casting a by means of set-screws e, which pass through slots f in the plate or bar (Z and are screwed into the casting a. On the bar (Z is formed an upwardly-projecting pointer and stop 9. In setting the gage the set-screws are loosened and the plate or bar (Z is adjusted until the pointer 9 reaches the mark indicating the number of bushels it is desired to sow to an acre. The set-screws are then tightened and the levers l6 moved upinto engagement with the pointer g, which also forms a stop for said levers. When the levers 16 are in position against said stop, the plates 16 will have been adjusted thereby to regulate the size of the feed-openings to sow the amount of seed indicated by the pointer to each acre of ground.

The scale-bar 0 is rotatably mounted in the casting a by forming on one end of said. bar a bearing-pin h, which is adapted to enter a hole or recess in the side walls of said slot. In the other end of said bar is formed a hole or socket i, into which is adapted to be engaged the end of a setscrew k. which is screwed through one end of the casting and into the said hole or socket By loosening the screw the scale-bar 0 may be turned to bring the desired face or side of the same to the front.

In the lower portion of the hopper, below the partition 13, is arranged a transverselydisposed shaft 18, the ends of which are journaled in bearings on the frame 6, and by this shaft the hopper is pivotally connected to said frame 6. One end of the shaft 18 is extended and has mounted thereon a spur gear-wheel 19, which is adapted to mesh with a similar wheel 20, fixed on one of the hubs of the supporting or ground wheels, whereby motion is imparted to said shaft. The gear-wheels19 and 20 are preferably inclosed in a housing or casing 21,as shown in dotted lines in Fig. 1.

The main portion of the shaft 18 is square, and on the same is slidably mounted four or more seed discharging cylinders 22, which are connected together in pairs by bars 23, which engage and slide on the upper sides of the shaft 18, said sliding movement being lin1- ited by pins or screws 24: on the shaft 18, which engage slots 25 in the bars 23.

The seed-discharging or feed cylinders 22 each have formed on their surfaces two annular series of seed-pockets 26 and 27, the pockets 26 at one end of the cylinder being longer and larger than the pockets 27 at the opposite end. The feed-cylinders 22 are adapted to be shifted to bring either of the series of seedpockets beneath the feed-openings 15 in the partition 13 to facilitate the discharging of different varieties of seed.

In Figs. 1 and 2 of the drawings I show a harrow 31 arranged under the seeder or planter and provided with a roller 45. Chains 17 connect the front portion of the harrow to the seeder or planter. Chains 5 1 are connected to theharrow, near the center thereof, and pass over direction-sheaves 55 and are attached to winding-gun. 56. The latter is operated by a lever 58 and is controlled by a ratchet and pawl 57 60, respectively. By this means the harrow may be raised or lowered, as may be desired.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the prin ciple or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A seeder or planter having a hopper provided with a horizontal partition having discharge openings, longitudinally movable cut-off plates disposed one above the other and under the partition and provided with openings to register with and vary the operative area of the discharge-openings of the hopper, and means to simultaneously adjust the said cut-off plates in opposite directions,

reference to the lever that the lever may be caused to move across any of the scales on the gage, substantially as described.

In testimony whereof I have hereunto set 5 my hand in presence of tWo subscribing Witnesses.

CARL AUGUST JOHNSON.
